Relative humidity (% RH)
Relative humidity (% RH)
During the design of the data center, consider ease of entry for the equipment, floor loading factors, and
accessibility to piping and wiring. In addition, the room temperature and humidity combination should
conform to the environmental operating envelope as defined in the following graphics.
Ambient temperature (°F)
Seal the room with a vapor barrier to minimize moisture infiltration. Polyethylene film is recommended
for ceiling and wall applications. Apply rubber- or plastic-based paints to concrete walls and floors.
Insulate the room to minimize the influence of exterior heat loads. Reduce fresh air to the minimum
required by local and national codes and regulations. Fresh air imposes extreme load variation on the
cooling equipment from summer to winter and causes increased system operating costs.
Air distribution
The equipment distributes air in a back-to-front discharge pattern, removing hot air from a hot aisle and
discharging cooled air into a cold aisle.
Note: The equipment is designed for free air discharge or for use with the Rack Air
Containment System or Hot Aisle Containment System. The equipment is not intended to be
connected to a duct system.
Incoming power supply requirements
Automatic Transfer Switch (ATS). The function of the ATS is to
transfer the load from feed A to feed B if the power is lost on feed A.
na2252a
• Feed A (Primary Power Feed) supplies power to all functions in the
equipment.
• Feed B (Redundant Power Feed) supplies power to all functions in
the equipment.
Feed A
Feed B
CAUTION
ELECTRICAL HAZARD
The equipment requires three-phase electrical service. Electrical service must conform to
local and national electrical codes and regulations. The equipment must be grounded.
Failure to follow these instructions can result in equipment damage.
InRow RC Installation
11
Service access
An area of minimum 900 mm (36 in) of clear floor space in front of and behind the equipment is
recommended for servicing (208V equipment), or 1067 mm (42 in) for servicing 400V and 480V
equipment. All required normal maintenance can be performed from the front or rear of the equipment
while in the row.
An area of minimum 1200 mm (48 in) of clear floor space in front of or behind the equipment is
recommended to roll the equipment out of a row.
Note: Check local and national codes and regulations for further service access requirements

Joining the Equipment to Enclosures
Joining to NetShelter™ SX enclosures
The equipment comes with four joining brackets (two for the front and two for the rear).
1. Remove the front and rear
doors. See “Removing the
front and rear doors”.
ns0618a
2. Locate the four joining
brackets. Rotate each bracket
ninety degrees toward the
adjoining enclosure so the
bracket is parallel to the floor
and install using the screws
provided with the enclosure.
For more information, see
the Unpacking, Installation, and Customization manual for the NetShelter SX Enclosure.
Joining to NetShelter VX and VS enclosures
For information on joining the equipment to NetShelter VX and VS enclosures, see the
installation sheet NetShelter™ SX to VX or VS External Joining Kit—AR7601, AR7602.

Condensate pump
The pump is factory-wired and
piped internally to the condensate
drain pan. The pump can move
liquid a maximum of 18 m (60 ft),
which may include a maximum lift
of 3.5 m (11.5 ft) at a flow rate of
87 l/hr (23 gph). For example, if
your lift is 3 m (10 ft), you will
have 15 m (50 ft) of usable run
remaining. The pump uses an onboard condensate high level float
switch wired into the equipment
for alarm capabilities.
Connection
through top
Connection
through bottom
The condensate drain line can be connected through either the top or the bottom of the
equipment using factory-installed male quick connectors and tubing approved by local
building codes that will allow the drain line connector to be moved approximately 25
mm (1 in) away from the equipment. This facilitates removing the equipment from a
row. Female quick connectors and reduction fittings are supplied with the equipment.
Connect the fittings as shown, then connect the drain line quick connector to the top or
bottom condensate pump output line.
Tubing (field supplied and installed)

Electrical Connections
The following electrical connections are required in the field:
• Controls (user interface, Network Management Card)
• Communication (A-Link, Building Management System)
• Power
All electrical connections must be in accordance with local and national codes and regulations.
See the equipment nameplate for voltage and current requirements.
All low-voltage connections, including data and control connections, must be made with properly
insulated wires. Low-voltage wiring must be insulated based on the wiring with which it is routed.
Wiring does not require 300-V insulation if it is separated from line voltage wiring. However, it will
need 600-V insulation if it is wired in the same cable tray as 480-VAC wiring.
WARNING
ELECTRICAL HAZARD
Potentially dangerous and lethal voltages exist within this unit. More than one disconnect
switch may be required to energize or de-energize this equipment. Observe all cautions
and warnings. Failure to do so could result in serious injury or death. Only qualified
service and maintenance personnel may work on this equipment.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
CAUTION
ELECTRICAL HAZARD
• Three-phase (plus ground) electrical service is required. Electrical service must conform
to local and national electrical codes and regulations. The equipment must be grounded.
Check the nameplate for correct Full Load Current and Minimum Disconnect Size.
• Before making any electrical connections, make sure that the unit is turned off and
locked-out. Lockout/tagout represents safety procedures that remove access to a device
and physically labels the device as intentionally out of service.
Failure to follow these instructions can result in equipment damage.

Water outlet temperature sensors
There are two water outlet temperature sensors, one
for top connection and one for bottom connection.
These sensors are wired to the main board on the
electrical panel.
Top connection: Wire with
green tie wrap in J23
The unit is delivered with top connection as the
default configuration, i.e., the wire with a green tie
wrap is positioned in connector J23 (marked with
green) on the main board. If the configuration is
changed from top to bottom, switch the wire already
positioned in the connector J23 with the wire labeled
with a green and a white tie wrap. This wire is part of
the wire harness inside the electrical panel.
Bottom connection:
Wire with green and

Communication connections
A-Link connections. The A-Link bus connection allows communication between cooling units. Only
one InRow RC needs to be defined through the display. The numbering of the other InRow RCs (up to a
maximum of twelve) will take place automatically.
To enable the equipment to work as a group, link the units using the supplied cables or CAT-5 cables
with RJ-45 connectors as shown. Terminators (120 Ohm, 1/4 W) must be inserted into the open A-Link
